Novel perfluoropolyether derivatives are described which are obtained from perfluoropolyethers having a carboxyl group at one or both ends and monoamines or diamines. The derivative is useful as a lubricant owing to its significantly improved lubricity. The lubricity is shown under severe high or low temperature and humidity conditions over a long term. The derivative is especially useful as a lubricant for magnetic recording mediums of the coating and metal thin film types.
